Gavin Verhey brought Corey Bowen, the lead designer on Commander 2020, to give a deck tech on his Marchesa, the Black Rose deck built around modular.
Bowen lays out the deck and goes over the artifact creature theme and highlights the powerful cards in all the meaningful categories of Commander must-haves.
Bowen described the deck on the higher side of power level, but not pushing the boundaries of a casual game. A full decklist for the deck can be found in the description of the video.
